Pulley assembly and wardrobe

technical field

The invention relates to the technical field of furniture, in particular to a pulley assembly and a wardrobe.

Background technique

At present, the more common structural forms of glass doors, room doors, and wardrobe doors in furniture are sliding doors. The hanging sliding door is generally equipped with pulleys on the bottom and bottom of the door panel, and moves in the guide rail. The existing hanging sliding door has a single function and only has a sliding function. In fact, hanging sliding doors are prone to the phenomenon that the height of the door panel does not match the cabinet body or the door panel is tilted. The tilt refers to the unevenness on both sides of the door panel. For example, the height of the door panel and the cabinet body does not match or the door panel The phenomenon of tilting, or the phenomenon that the door panel sinks or tilts due to the wear or loosening of parts after long-term use often occurs. The current countermeasure is to disassemble the door panel and reinstall it. This solution is time-consuming and labor-intensive, and brings inconvenience to users.
